(-3,9) on a coordinate plane

1 answer:

7 0

So what you want to do is for -3 go to the centre of the coordinate plane and move 3 to the left, then you want to move it up to 9

And there you have it. hope this helped :)

1 2/3 divided by 3/16

5/3 / 3/16

KCF (Keep, Change, Flip)

5/3 * 16/3

5 * 16 = 80

3 * 3 = 9

5/3 * 16/3 = 80/9

8 8/9

Determine the radius and center of the circle with the following equation <br> x^2+y^2-12x+24y-10=6

PolarNik [594]

Answer:

Center: (6, -12)

Radius: 4

Step-by-step explanation:

<u>Complete the squares</u>

<u /> $x^2+y^2-12x+24y-10=6\\\\x^2-12x-10+y^2+24y=6\\\\x^2-12x-10+46+y^2+24y+144=6+46+144\\\\(x^2-12x+36)+(y^2+24y+144)=196\\\\(x-6)^2+(y+12)^2=196$

Comparing with the standard form equation $(x-h)^2+(y-k)^2=r^2$ , since $r^2=196$ , then the radius of the circle is $r=14$ . Also, the center of the circle would be $(h,k)\rightarrow(6,-12)$ .

You need a 75% alcohol solution. On hand, you have a 1125 mL of a 90% alcohol mixture. How much pure water will you need to add

Alex777 [14]

$\bf \begin{array}{lccclll}
&amount&concentration&
\begin{array}{llll}
concentrated\\
amount
\end{array}\\
&-----&-------&-------\\
\textit{90\% sol'n}&1125&0.9&(1125)0.9\\
\textit{water}&x&0&0x\\
-----&-----&-------&-------\\
mixture&y&0.75&0.75y
\end{array}$

so.. whatever "x" is, we know 1125 + x = y
and whatever the alcohol concentration yield may be, we know

(1125)(0.9) = 0.75y

(1125)(0.9) = 0.75y <--- solve for "y", that's how much the final amount of milliliters will be

how much pure water was added? subtract 1125 from that, or y - 1125
